What is the disadvantage of raise dead+restoration against true resurrection?When you're high enough level to properly cast True Resurrection on your own, a difference of 20k gp here or there is small change; high level characters have absurd quantities of wealth to throw about. Remember that money that you spend so that you don't keep it (food, bribes, spell components, etc) is to be eventually rewarded again to keep your wealth by level up.

Calculating and balancing challenge ratingsAh, yes, EL not ECL, my mistake. Write it wrong once and keep making the same mistake the whole way through, silly me. As to the idea that "EL doesn't exist in Pathfinder", well that's just absurd. Pathfinder is based on 3.5 with a million little edits. There aren't enough changes to the fundamental math to affect how the CR system works (that would break backwards compatibility), and so the same rules apply to all of 3.0/3.5/PF.
